Provide an option to fit to screen or fit to macro and remove the board title and modification note for the selected frame/board embedded in Confluence so there is not such a large border of the gridline background.
It eats up a lot of real estate that could be used for other purposes on a Confluence page.
EXAMPLE: The image below is a screenshot from a Miro board embedded on a confluence page. I don’t need to see the gridlines or the board name.
